Who writes
Texts on this site carry one of two bylines. “Réda Haiat”, founder of CEFRHub, signs the texts he wrote or approved as author: the methodology, the CEFR descriptor pages and one article. Other texts are signed “CEFRHub Team”.
Our sources
Every claim rests on a source the reader can check: the CEFR and its Companion Volume (Council of Europe, 2001 and 2020). For other exams and frameworks, they are the documents published by their bodies, for example IELTS, ETS for the TOEFL, or ACTFL; the equivalency pages cite them and link to them. CEFR descriptors are quoted in short excerpts, credited to the Council of Europe, with a link to the official document.
What we do not write
No invented figure, client, logo or testimonial, and no measure of accuracy that has not been published. No text copied from a competitor: when a page describes another exam or tool, it relies on what that body publishes itself. We criticize market problems, never institutions, public bodies or individuals.
Approval before publication
Every page is reviewed and approved by Réda Haiat before it is published. The Methodology page publishes the grid the tool applies: an automated check makes sure it stays identical to the tool's grid.
Content about CEFRHub
CEFRHub is a commercial product. The guides explain the CEFR and its uses. Pages that present CEFRHub or compare it with other tools say so in their title.
Dates and corrections
Each article shows its publication date; the date of its last update is in its metadata. If you spot an error, write to contact@cefrhub.ai: we check it and correct the text.
